Specification of Letters Patent.

Patented Nov. 26, 1907.

Be itknownthat I, RICHARD M. PAxToN,

-a citizen" of the United States, residing at Washington, in the county of Washington and State of'Pennsylvania," have invented certain new and useful Improvements in Glass-Working Apparatus, of which the following is; a specification", reference being had I therein to the accompanying drawing.

- My invention relates to improvements in glass working 'a paratus, and pertains to a mechanism for orming a blank from a predetermined quantity of molten glass, to be afterwards blown into the finished article in any well known manner.. v

The-primary object of my improved ma (chine is to do away withthe usual gathering and pressing of the molten glass previous to the blowing operation.

In the accompan g drawings, Figurel,

. is a top plan view my. improved apparatus for forming blanks from a predetermined quantity of molten glass. .Fig. 2 is a transverse vertical sectional view taken on the line a:-m of Fig. 1.- Fi 3, is an enlarged verticalsectional View ta en on the line y 'gz of Fi 1. Pi 4, is an enlarged vertical sectiona view 0 the plungeri'and blow head? Figs. and 6 are vertical sectionalview's of modifications of the neck ring, and means for holding the molten glassi'n the mold. I Referring now to the drawings, 1 is a glass furnace and extending through the wall 2 35' I 'the furnace 1, as shown at 4, and also out-' side ofthe furnace, as shown at 5. Extendthereof is a-block 3 of suitable material. The block hasits innerend projecting into .ing diagonally throughthe block 3 is'an outlet passage-way 6, the inner endof which communicates with the glass furnace at a,

point below the lass level, and its outer end 7-is outside of t e furnace, and a sufficient distance". from, the outside of the wall 2 to enable a mold9 to be placed under the block and register'with said'opening, as will be.

hereinafter morefully described.-

' A suitable distance from the tank I provide avertically disposed standard 9 mounted upon the base 10, and rigidly carried there by. Rotatably mounted upon said standard is a hub 11 which is provided with the raidally-extending arms 2 which, as shown,

' will be six in number, although any desired number may be used, as will also, be herein- "after. more fully described. Rotatably mounted upon said standard9 above the hub normal vertical position.

11, but secured thereto, is an elongated huh 5 13 which is provided at its u per end with radially-extending arms 14 w h are six in number, and arranged directly above the arms 12. Secured to the lower end of the upwardly and are secured to the outer ends 0 the arms 13. Q

- Secured to the under side of tlie outer end of the block 3 is a late 15 which is of any suitable metal, an this plate is provided hub 12 are the brace arms 15 which extend with an opening 16 registering with the outer end 7 of the passage-way 6, and thus'the plate 15, in conjunction with the upper end glass, as will be full describe a The outer ends 0 the arms 13 are .rovided with broad vertical faces17 to whic. are ro- 1 tatably, secured the vertical 'plates 18 by means of bolts .19, and thus the plate Ina be oscillated for inverting the mold 8, as 1 be hereinafter more fully described. The outer 7 face of saidplate 18 has laterally'extending ears 20 and 21 through which passes the ver-' tically-disposed bolt 22. Pivotally carried vby the said bolt 22 between the ears are cars 23 and 24 carried by the mold sections 25 and 26, and thus the mold sections are supported u on the bolt 22 so as to oscillate, and thus t e' sections can be movedfor opening the mold for removing the blank. The outer faces of the mold sections are provided with outwardly-extending interlocking ears 27and 28 through which passes a locking key or pin 29, whereby the mold sections'are held in their closed relation. a

The inner face of the plate 18 is provided with an opening 31 in which the outer end of the spring-pressed pin 3 2.is normally held, and by means of which the mold is held in its This pin 32 passes through a housing 33 carried by the arm- 13, and in which is mounted the spring 34. The inner end of the pin 32 passes through the housing and is provided with a knot or handie 35 by means of which the inner end of the of the mold, causes a shearin action on the wherebygthe neck ring maybeopened.vv The outer ends of the ring sections are provided with interlocking ears 43 and 44 through which passes the locking pin 45 for holding the neck ring in its closed position. The neckring, as is readily seen, is held in the lower-end of the mold when the same is closed, by the bevel portion 37 and cannot be removed when the mold is closed.- When the mold is opened, the neck ring is then looked upon the glass blank for handling the same, and is removed therefrom bv withdrawing thegpin 45. v i

The upper end of the mold 8 .extendsupwardly against the lower face of the plate 15,

and after the mold is filled with molten glass and the mold-moved to the next position, there is a shearing action between the upper end of the mold and the plate 15,'which cuts the glass and leaves the mold filled with glass up to the upper ed e.

The upper end 0 the plate 18 has secured thereon by means of a screw 46, a circular cap 47 which is provided with a circular de-,

pression 48 in which rests an enlarged circular end 49 of the arm 50, and covering said enlarged end is a plate 51 screwed on the cap," and rotatably supporting the arm 50 thereon.

The outer end of said arm is provided with an. enlarged circular portion 52 which is adapted to be swung around and cover the upper open end of the mold after it has been moved out from under the block extending- 'from the tank and adapted to hold glass Within the mold when the same-is inverted.

The several molds being carried by the radially arranged arms 15 are arranged in a circle so that each mold may be brought below the block 5 to be filled with molten glass.

In order to prevent the molten metal from' passing from the lower end of the opening 7 during the rotation of the frame for moving one mold from under the block, and bringing the next mold in position to receive the molten metal, I provide the space between the molds with segmental plates 53 which are supported by arms 54- carried by the arms 13. The'said plates'are supported in a plane with the upper face of the-molds, and thus close the lower end of the opening 6 during the rotation of the table from one mold to the succeeding one. As clearly-shown, the plates .53 form a circular table, leaving a space sufficient to allow the molds to be inverted.

. 'Theupper ends of the mold sections 25 and 26 carry the plates 53 which are preferably cast as a part of the mold sections, and are flush with the upper end thereof.

plates 53 have their upper iaces in a plane The said with the table 53 andform a continuation thereof to prevent the molten glass from passing from the opening 6 in the tank. The

space between the plates 53'and 53 being sufficient to allow the mold sections carrying the same to berevolved or inverted;

beforedescribed, the arms 12 are the adapted to revolve with the same.

same in number as the arms 13, and are arranged directly below the same, and are The outer ends of said arms are provided with cylinders 55 which are arranged directly below the lower open end of the molds. The said cylinders are'provided with pistons having the upwardly-extending piston rods 356 which are provided at their upper ends with the plugs 57 which are adapted to be raised by compressed air or steam within the cylinders through the medium of the piston rod,' and close the lower end of the mold. The

' said plug or blow-head for blowing the initial openin in the blank is'formed as clearly,

shown in Fig. 4. The upper end of the piston is provided with anfannularflange 58 to which. is screwed the plug 57. The said "plug is .provided' wi'th an enlarged central I longitudinal opening 59 which has its loWer through which a vacuum is created within I the opening 59, and said opening hasa series of openings 62 communicating with the interior of the mold and draws or sucks the molten glass down within the mold and holds operation, as I will now proceed to describe.- Extending through the ipe 61. is a small compressed air pi e 63 w 'ch extendswi thin the opening 59 o the plug and extends upwardly and communicates with an" opening 64in the upper end of the head, and through which the compressed .air is forced forblowinglthe initial opening in the blank.

In operation, a mold is brought below the the same therein during the initial blowing opening 6 inthe block .5 and simultaneously the. steam is admitted through the pipe v65 to the cylinder 55 which forces the piston rod 56 upward and forces the plug 57 Within the neck ring and tightly closes the lower end thereof, the vacuum drawing the glass within the mold. The table is then revolved which shears the glass, leaving the mold full of molten glass. In this'second position, the plate is then swung over to,cover,the open upper end of the mold. The vacuum through the small openings 62 firmly holds the neckof the blank bottle within the neck ring, and compressed air being admitted through the pipe 63, blows the initial opening in the lank. In the next position caused by the rotation of the table, the pin 35 is pulled 'outward, releasing the plate 18 and allowing the same to be oscillated so that the mold is from passin from the mold. In this position, the mo (1 is opened, allowing the blank to be-removed by the neck ring when it is afterwards putthrough the finishing blowing ro cess'.- I have shown six molds which al-v owv'r of the. cooling of the same before if? j reaches the filling position again, and also gives :ample .time for the'closin and placing of the neck ring in'th elower-en of'the mold. In Figsi-5 and 6, instead of the neck ring ried y the plug and automatically coupled to the mater- ,11 this form there is arranged a standard'66 adjacent the block 3, and proyided with asleeve' 67 which is normally held downward bythe spring 68 upon the stop 69. The said sleeve 67 is provided with an outwardly-extending arm 70 which is provided with an enlarged portion 77 at its .outer end,

' V which is located in a vertical line directl be low: the'opening in' the block. In this orm,

the mold section 72 at its lower end is pro- Vided with a beveled recess 73 which forms a guide for coupling the neck ring 74 thereto.

The neck ring 74 is'provided with an upwardly-extending beveled extension 75 which is adapted to engage the beveled wall'74 of the lower end of the mold' section, and cause the same to center itself within the mold. The beveled end 70 of the hooks 76 are on- 'gaged by the side ofthe neck ring and forced outward until the hooked end passes the.

{lower end of the ring, when they spring inward and firmly lock the neck. ring to the mold;

. In operation, in using the modification, the

mold is brought below the opening in the block, and the plate 77 will be directly below the lower .open end of .the mold... The plunger isthen forced upward which engagesthe plate 77, forcing the same upward I ,as'heretofore described.

' I-claim'and desire to secure by Letters Patent,is:

The table is then started to revolve, shearing the glass .at.the upper end of the mold, and at the same time the plunger is retracted and the spring 68forces the plate from below the Having thusdescribedmy invention, what 1-.
